Publication number: 20140001872Abstract: A power switching circuit is connected to an external power source, a battery, and a load. The power switching circuit includes a voltage converter, a prevention unit, a detecting unit, and a switch. The voltage converter converts a first primary voltage supplied by the external power source to a secondary voltage. The prevention unit allows the secondary voltage to be transmitted to the load, the secondary voltage powering the load. The detecting unit generates a first level signal when the external power source fails to output the first primary voltage. The switch is turned on to transmit a second primary voltage supplied by the battery to the load and the prevention unit in response to the first level signal. The second primary voltage powers the load. The prevention unit prevents the second primary voltage from being transmitted to the voltage converter.Type: ApplicationFiled: April 24, 2013Publication date: January 2, 2014Applicants: HON HAI PRECISION INDUSTRY CO., LTD., HONG FU JIN PRECISION INDUSTRY (ShenZhen) CO., LTD.Inventors: JIE-SONG ZHOU, AN-BANG YU

Patent number: 5986483Abstract: A direct digital frequency synthesizer outputting a sine signal is disclosed, comprising an accumulator, a symmetry circuit, a coarse circuit, a fine circuit and a sign circuit, wherein the accumulator sequentially outputs a sample address according to a frequency control signal. The symmetry circuit takes the complement of the sample address according to a first clock, the period of the first clock being twice the period of the first MSB of the sample address, to obtain a symmetric sample address represented by N bits. The coarse circuit connected to the symmetry circuit outputs the first M MSBs of the symmetric sample address as the first M MSBs of the sine signal. The fine circuit predicts the last N-M LSBs of the sine signal from the last N-M LSBs of the symmetric sample address according to the first M MSBs of the symmetric sample address of the coarse circuit.Type: GrantFiled: December 1, 1997Date of Patent: November 16, 1999Assignee: National Science CouncilInventors: Tzong-Bang Yu, Shen-Iuan Liu, Hen-Wai Tsao
